BOURBONNAIS, Ill. -- Chicago Bears defensive end Corey Wootton used Twitter on Tuesday to inform fans he underwent surgery to repair meniscus damage in his right knee.
"Thank you everyone for all your thoughts and prayers," Wootton tweeted. "The scope went well... (I'll) be back soon!"
A second-year player from Northwestern, Wootton is still expected to miss up to four weeks after Tuesday's arthroscopic surgery, according to league sources.
Wootton suffered the knee injury on the opening kickoff of Saturday's 10-3 victory over the Buffalo Bills in the preseason opener at Soldier Field. Sprinting down the field, Wootton planted his right leg awkwardly upon engaging a block by a Bills player.
The team immediately declared Wootton out for the duration of the game.
Wootton's injury should sideline him for the rest of the preseason, putting somewhat of a kink in the tremendous progress the defensive end appeared to be making during training camp, while opening the door for free agent acquisition Vernon Gholston to receive more repetitions.
Defensive coordinator Rod Marinelli had been complimentary of the progress Wootton had shown.
"Just knowing what to do, knowing where to go fast, all those things," Marinelli said. "He's got great tempo, he's smart, and he's really trimmed himself down; looks quick, looks fast. The more you do something, the better you get at it just doing it over and over. I like what Wootton has done so far in camp."
The progress seemed to be a continuation of what Wootton had done toward the end of his rookie season. Inactive for 10 of the first 12 games, Wootton played in each of the last four games, contributing five tackles and a sack against Minnesota on Dec. 20 that knocked former Vikings quarterback Brett Favre out of action.
Wootton's sack would go down as Favre's last snap in the NFL.
