Detroit Lions running back Jahvid Best missed practice Sunday after suffering a concussion during the first series of Friday's preseason game in Cleveland.

Best caught a swing pass from quarterback Matthew Stafford on the first play of the game and took a helmet-to-helmet hit along the sideline from Browns cornerback Joe Haden. He stayed in for two more plays, the second being a fumble, and was then removed from the game.

The second-year running back has dealt with health problems, including two turf toes that limited him as a rookie and a concussion in college that ended his junior season prematurely. Best, who played at Cal, entered the NFL draft after his junior season.

"We'll take it slow with him just based on his situation from a couple years ago and we'll just be very, very cautious with him," Detroit head coach Jim Schwartz said. "But we should have him back on the practice field soon."

Best ought to be okay for the start of the season. He is a bit of a boom or bust pick because of his past durability issues, but if he can stay healthy, he's an unquestioned boomer.

Quarterback Colt McCoy threw three touchdown passes - two to tight end Evan Moore - in the first half, but Cleveland blew a 15-point lead, losing 30-28 to Detroit in a penalty-filled exhibition.

McCoy finished 10 of 18 for 96 yards, his second straight solid performance running first-year Browns coach Pat Shurmur’s new West Coast offense. McCoy was victimized by a few drops but didn’t force any throws while playing most of the first half.

The Lions trailed by 10 entering the fourth, but got a 20-yard TD pass from Drew Stanton and Dave Rayner’s 48-yard field goal.

The officiating crew had a busy night: The teams were assessed 26 penalties for 211 yards.

Moore caught TDs of 2 and 21 yards, rookie Greg Little grabbed a 13-yarder from McCoy, and rookie Armond Smith had an 81-yard TD run in the third for the Browns.

Detroit quarterback Matthew Stafford threw one TD pass to Nate Burleson. Stafford went 6 of 10 for 85 yards in four series.

McCoy, with four touchdowns passes in two preseason games, is doing everything he can to earn consideration as a legitimate QB2.

Detroit Lions wide receiver Calvin Johnson left Friday night's preseason game against the Cincinnati Bengals after he ended the first drive with a 26-yard catch. Johnson leaped for a high throw from Matthew Stafford and came down in the end zone on his left shoulder. He was seen getting treatment on the sideline but did not have it wrapped after the game in the locker room.

"It's all right," Johnson said. "I just came down on it. It's just sore right now. But it's all right."

Johnson joked that he had earned his time off.

"We go down and score on the first drive," he said. "We go down and score on the second drive. I think the starters deserved to come out."

This shouldn't be a concern going forward.

Detroit Lions quarterback Matthew Stafford threw touchdown passes on his two drives, while backup quarterback Shaun Hill ran for a score and Jason Hanson kicked a field goal to give Detroit a 24-3 lead at halftime. They ended up routing Cincinnati 34-3.

Bengals quarterback Andy Dalton was hit by Ndamukong Sung after taking his first NFL snap and Chris Houston intercepted the underthrown pass. Dalton, a second-round pick, finished 11 of 15 for 69 yards. He put Cincinnati in a position to attempt two field goals and Mike Nugent made one to make it 14-3.

Stafford was 6 of 7 for 71 yards. He threw a 26-yard TD pass to Calvin Johnson, who didn’t return to the field, and a 7-yarder to Nate Burleson for another score on an overturned play.

A very good start for Stafford, even if it was against the Bengals. If he can stay healthy, he'll be a very solid fantasy quarterback.

Lions QB Matthew Stafford: I’m going to play all 16 [games], I’ve got Calvin Johnson, Nate Burleson, Brandon Pettigrew. I’m throwing the ball to Jahvid Best and Leshoure out of the backfield. I feel there is going to be a lot of points put up.

A second-round pick out of Illinois, Mikel Leshoure joined teammates and free-agent cornerback Dre Bly for Day 1 of the second set of player-organized workouts Monday at Birmingham Detroit Country Day.

He sat out some of the practice with a cramp and kept his bruising running style under wraps in a no-contact workout, but he still caught the eye of cohorts.

"He's a big kid," quarterback Matthew Stafford said. "He's what I expected to see, which is good."

Said receiver Derrick Williams: "He looks like he's a beast. He has that look. And when he was in college he was definitely someone to be afraid of. I wasn't on defense, but some of my guys (at Penn State) were like it was hard to tackle that guy."

Matthew Stafford's Lions worked out at Detroit Country Day School on Monday, the same place they gathered a few times last month. About 25 Lions were on hand, including two second-round picks from the team's 2011 draft. Wide receiver Titus Young and running back Mikel Leshoure both were about as wide-eyed as expected.

"I don't think they overwhelmed us with too much," Leshoure said. "There's no playbooks for me to just go home and study. We're going to take it bit by bit." "To tell you the truth, it was a little bit more organized than I expected. I figured it would just be run by the players. For guys to be here to help us out, that's a blessing."

Lions president Tom Lewand says QB Matthew Stafford's recovery, according to the trainers, is "off the charts."

You can see the difference immediately. Detroit Lions quarterback Matthew Stafford, who was taking part in a players-organized workout today at a local high school, is much thicker through the chest than he's been the last two seasons.

"That's 10 weeks of upper body (training). It was an emphasis,'' Stafford said.

Lions quarterback Matthew Stafford, representing Detroit in his Tigers cap, looked strong in his first public passing display since undergoing shoulder surgery in January.

“It felt good,” Stafford said of his shoulder. “It was fun. We just had a good time out here today — nothing too crazy, just fooling around a little bit. It’s good to be back here at Sanford Stadium in front of these great fans. This was a great turnout and a great day to be out here.”

Up against fellow Georgia quarterback legends and NFL veterans Eric Zeier, David Greene and D.J. Shockley, Stafford threw 12 passes in the competition and turned in the top score in two of the three events.
