In the second quarter of the San Diego Chargers game against the St. Louis Rams, tight end Antonio Gates headed to the sidelines with a left ankle injury. He was in the locker room for all of the second half. Gates was injured during a block on a carry by running back Ryan Mathews. "I got tripped up and I guess some guys fell on the back of my leg," said Gates, who was wearing a walking cast in the locker room. "That's initially how it started. Then on a pass down the middle on the last play I was in, someone fell on my ankle. I just couldn't go. I couldn't move." Head coach Norv Turner is not aware of how serious the injury is. "Antonio couldn't come back. I don't know the extent of it (his injury). I know it was serious enough that he couldn't return," Turner said. "Hopefully, it's not a long-term deal."

Fantasy Analysis:

If a guy is unable to even return to the sideline to watch the game, needless to say, the team is concerned. Gates will undergo an X-ray and MRI on Monday back in San Diego. Until some official results come in from those tests, it's all speculation but it's never too early to grab a tight end on the waiver wire as some insurance. Gates has been the best tight end in the game this season so he'd be a big loss. From the looks of the injury, he'll be fortunate to have only sprained it. If he only misses one week, in my opinion, that'd be very good news because it looked serious on replays.
