Patriots Center Ted Karras -- Knee
Patriots center Ted Karras was the only New England player to have played 100% of his unit's snaps this season, but he injured his MCL against the Texans and is expected to miss time. At the very least, Karras is likely to miss Week 14's game against the Chiefs; around 80% of MCL sprains to offensive linemen result in at least a one-week absence. Pending MRI results, our numbers give him a 50/50 chance of missing the rest of the regular season too, as around half such injuries cause an absence of four weeks or longer. Some offensive linemen return early with the aid of a knee brace, but even if he cannot, we cautiously expect Karras to return in time for the team's first playoff game.
Colts Receiver Chester Rogers -- Knee (IR)
Chester Rogers fractured his knee against Tennessee and is expected to miss the rest of the season, though he awaits confirmatory scan results. Rogers has started six games for the Colts this season, mostly during the absence of T.Y. Hilton, but remains under 200 yards receiving.
The following players left their respective games with concussion symptoms and enter the league protocol:
- Broncos guard Ronald Leary
- Giants cornerback Cory Ballantine
- Jets cornerback Brian Poole
- Panthers tight end Greg Olsen
- Redskins receiver Trey Quinn
Based on our current data, a growing majority of players now miss at least one game following a diagnosed concussion, but around 80% return within two weeks.
Broncos defensive end Derek Wolfe has been placed on injured reserve with an elbow injury, ending his season. Wolfe is a free agent this offseason and should be fully healthy in time for the new league year.
Chiefs halfback Darrell Williams injured his hamstring. Most hamstring injuries to running backs cause at least a one-week absence, but 75% of players return within three weeks. A similar prognosis applies to cornerback Rashad Fenton, who also injured his hamstring.
Jets cornerback Arthur Maulet is considered week-to-week after straining his calf against the Bengals. A narrow majority of cornerbacks do not miss time after suffering a calf injury, and 85% are back on the field within two weeks. Safety Jamal Adams sprained his ankle and awaits MRI results. He is expected to miss practice on Wednesday at the very least.
Lions tight end T.J. Hockenson has been placed on injured reserve due to his lingering ankle injury.
Texans halfback Taiwan Jones injured his hamstring. As noted above, most hamstring injuries cause at least a one-week absence, but 75% of players return within three weeks.
