The rookie wide receiver reportedly did not have any after-effects, as he was ready to go on Thursday:
SB Nation's Big Cat Country didn't sound too concerned about the situation.
It's good news for Jaguars fans, who had to suffer through a punchless offense in 2011 that featured a struggling rookie quarterback (Blaine Gabbert) with very few weapons to get the ball to in the passing game.
Blackmon, a two-time Biletnikoff Award winner at Oklahoma State, was drafted No. 5 overall to give Gabbert some help, but rookie WRs have one of the toughest transition processes coming out of college.
The last thing Blackmon needs in 2012 is a lingering ankle injury, so it will be something to watch closely on Sunday.
