Vernon Davis left Sunday night’s game on crutches, but he could be back on his feet soon.

According to Matt Maiocco of CSNBayArea.com, Davis avoided a serious ankle injury and could be back as soon as Sunday’s game against the Cardinals.

An MRI yesterday revealed a deep bruise, but no structural damage.

Davis wasn’t able to return to the game after being rolled by Bears linebacker Jon Bostic. That left them thin, with backup tight end Vance McDonald suffering a knee injury and Derek Carrier is the only healthy tight end on the roster.

Davis wasn’t able to return to the game after being rolled by Bears linebacker Jon Bostic. That left them thin, with backup tight end Vance McDonald suffering a knee injury and Derek Carrier is the only healthy tight end on the roster. Keep an eye on his progress this week. Davis has a potentially good matchup against the Cards who struggle to defend the TE. Since it's a late afternoon game, owners will still need a backup plan in place in case Davis can't go.

According to Matt Maiocco of CSNBayArea.com, tight end Vernon Davis missed the last 10 minutes of the game and was on crutches in the locker room with an ankle injury.

Davis came up hobbling after a hit by Bears linebacker Jon Bostic, in which is foot was caught underneath him. On the next play, Colin Kaepernick was picked off throwing to third-string tight end Derek Carrier. Backup Vance McDonald hurt his knee in the first half and was limited in the second half.

The story went on to say that 49ers coach John Harbaugh was asked about the condition of his Pro Bowl tight end but all he said was he didn't talk to Davis after the game. Obviously there will be tests today to determine his status, including a possible MRI. It wasn't a good night for 49er TEs as backup Vance McDonald was limited by a first-half knee injury. Third stringer Derek Carrier was forced into action as a result.

Rod Streater might be developing into Derek Carr's most reliable target. Streater had five catches against the Jets in coverage against five different defenders on six targeted passes. Clearly, Carr has confidence in him. It appears Streater earned that trust much more than Denarius Moore, who caught just two of eight targeted passes against New York. Coaches like the way Carr and Streater have connected in practice, and Streater said after the loss to the Jets that he loves the way Carr runs the offense and that he believes the rookie will get better quickly.

Streater was one of our favorite late-round picks after he posted #33 WR numbers in 2013. Look for more quiet production in the coming weeks.
