Sources: 49ers WR Brandon Aiyuk suffered a season-ending knee injury on Sunday, tests confirmed.

Anyone who held on to Jennings should be in good shape as he will likely slide in as the team's WR2 behind Deebo. Jennings didn't play in Week 7 because of a hip injury but the team is hoping to have in back for Week 8, according to reports. Pearsall was active for the first time and caught three balls for 21 yards. Cowing had two catches for 50 yards. Both rookies could be options behind Samuel, Kittle and likely Jennings, but may not be consistent fantasy producers. We reported McCaffrey is looking to return on Nov. 10 and it's possible he's counted on as a receiver more than a rusher once he's back.

49ers WR Trent Taylor is questionable to play Sunday against the New Orleans Saints, according to Nick Wagoner of ESPN.

Taylor is needed with Deebo Samuel out. The 49ers are dressing Brandon Aiyuk and fishermen from the local wharf. WR River Cracraft is also questionable with a quad injurt.

The end-of-game sequence was symbolic of an outing in which Jimmy Garoppolo seldom threw to his wide receivers and often was a tick off when he did. Three plays before the final incompletion to Trent Taylor, Garoppolo saw Kendrick Bourne all alone in the right corner of the end zone. His throw had too much loft, however, allowing cornerback Patrick Peterson to recover and break up the play.

Bourne and Taylor combined for four catches for 41 yards and were the only 49ers wideouts to catch a pass. The team’s would-be starters, Deebo Samuel and Brandon Aiyuk, were ruled out with injuries, and Samuel won’t be back until October at the earliest after going on injured reserve on Saturday.

The 9ers mainly targeted tight ends and running backs the story said. The story also added Aiyuk, who is recovering from a hamstring strain, was close to playing against the Cardinals.

Rookie wide receiver Brandon Aiyuk clearly established himself among the top – if not the top – wide receiver on the field during the first week of 49ers camp.

But Aiyuk’s status for the short term now is tenuous due to a hamstring injury he sustained during practice on Sunday morning.

The 49ers did not immediately provide an update on Aiyuk's status. Aiyuk and Bourne have established themselves as the top wide receivers with Taylor consistently playing in the slot. The 49ers hope to have Deebo Samuel back for the regular-season opener after he underwent surgery in June to repair a Jones fracture.

49ers GM John Lynch says on KNBR that he won't put a timeline on Deebo Samuel's return from a broken foot.

Lynch added according to the tweet, "It's fair to say he might miss some games at the beginning of the year." The 9ers may need Brandon Aiyuk, as well as Trent Taylor and Jalen Hurd to step up, at least early on. Aiyuk was a first round pick this past spring.
