Patterson told the media that Fields would forego the rest of the season and have surgery on his injured foot. A date for the surgery hasn't been set and will depend on Fields' class schedule.
Fields injured his foot against Texas Tech on September 12th and missed the SMU game while getting on the field for just a few plays against Oklahoma. Fields had totaled 4 tackles with 2 tackles for loss in limited action through three games this season.
Patterson said Fields' injury is similar to former TCU defensive end Stansly Maponga's injury last season that also required surgery.
"His foot has not gotten any better so what we're going to do is medical redshirt," Patterson said. "He's going to get operated on and get a screw in it, so he'll medical redshirt the rest of the season. He just can't play hard. The guy deserves to get back to full speed to where he can play."
Since Fields has seen limited action this season he's eligible for the medical redshirt but action in one more game would've voided that opportunity. According to Patterson, it was the best scenario for everyone to have the surgery now.
"He was great with it; it's hard for him and he's frustrated because he hasn't played to the level he can because of his foot," he said. "I think it's a win-win situation for us; it gives him three years left to play and allows him to get older and stronger and get that foot fixed right."
Fields' absence for the rest of the season doesn't help the depth at defensive end. Senior Matt Anderson has played well with Fields limited but Patterson also told the media on Wednesday that he's unsure if Anderson would see the field the rest of the season. Anderson didn't play against Oklahoma and speculation is that he has a hurt knee.
The silver lining however is that two sophomores have stepped up in Fields and Anderson's absence; Terrell Lathan and Mike Tuaua. Both defensive ends recorded a sack last week against the Sooners. Lathan is tied for the team lead in both tackles for loss (5.0) and sacks (3.0). He's recorded a sack in two consecutive games.
