New England Patriots QB Tom Brady has left practice with a knee injury. He is getting examined by trainers now. The whole sports world will be on Tom Brady watch.

Greg Bedard of SI.com watched Brady grab his left knee, limp off, before briefly returning to the field. Brady reportedly did not look comfortable and then had the knee checked out by trainers.

The whole sports world will also on

watch. It is Tim Tebow’s birthday today. Interesting that he could be getting extra reps now in practice with Tom out.

Everyone will be speculating about the ACL injury that Brady suffered in 2008 that caused him to miss the season. The extent of today’s injury still is unknown. He tried to practice again and didn’t feel comfortable. Will be interesting to see what the issue is.

Anytime the knee has been looked at there is cause for concern. This has been the offseason of ACL injuries. If Tom Brady were to go down for any amount of time, the whole football world could be flipped upside down.

UPDATE: Here is a fan video of when the injury occurred.
