Vernon Davis ankle injury not significant, per Matt Maiocco

The San Francisco 49ers may have dodged the proverbial bullet with Vernon Davis. The tight end suffered an ankle injury on Sunday, but Matt Maiocco is reporting the injury is not significant, and Davis could be back on the field this Sunday against the Arizona Cardinals.

Davis suffered the injury when he was tackled from behind, and the defender rolled Davis's ankle. He limped off the field, and did not return for the final ten minutes of the game. He was spotted on crutches after the game, and had an MRI on Monday. The 49ers will conduct their first practice on Wednesday, at which point we will see the first participation report. I expect Davis is either a DNP or limited on Wednesday. We'll see how his status evolves over the course of the week.

The 49ers signed tight end Xavier Grimble to their practice squad on Monday. He joined Asante Cleveland as emergency options in case the 49ers are short-handed on Sunday. Vance McDonald suffered a knee injury in the second quarter of Sunday's game. He returned in the fourth quarter for limited work before sitting out the fourth quarter.

That leaves Derek Carrier as likely the only tight end on the 53-man roster that is at or near 100 percent health. Carrier looked good in limited work, hauling in three receptions for 41 yards, including a sweet-looking 22-yard grab. Carrier came into the league as a converted wide receiver, with the expectation that he needed to improve his blocking. Garrett Celek remains on the PUP list with a back issue. He is eligible to return after Week 6, but there is no word on how his rehab is coming along.

Fooch's Update:

TE Vance McDonald says there's no structural damage to his knee, hopeful he can play Sunday vs. Cardinals. #49ers
