Injury roundup: DeSean Jackson sprains AC joint, Knowshon Moreno dislocates elbow

Sunday was a tough day for NFL stars.

A lot of key players were injured, beginning with Washington quarterback Robert Griffin III, who dislocated his ankle early in a 41-10 win over Jacksonville. Here are some other big-name players that went down during Sunday's slate of games.

DeSean Jackson: The Washington receiver landed hard on his shoulder and was ruled to have a sprained AC joint. He told reporters after Washington's win that he wasn't feeling pain at the moment and was hopeful of returning next week against Philadelphia.

Jamaal Charles and Eric Berry: The two Chiefs stars both sustained ankle sprains, with Charles only managing four yards on two carries before his exit from the game. According to Pro Football Talk, x-rays were negative for Charles, who will now have an MRI.

Knowshon Moreno: The Dolphins' running back dislocated his elbow, according to NFL.com, and will miss a month of game time at least. Lamar Miller will fill in as the starter and go-to back in the meantime.

A.J. Green: The Bengals star receiver injured his toe, though it appears to be a a ligament strain and not either turf toe or a broken bone, he told ESPN. There is a chance Green could come back next week, but if not, it's likely he'll be available in Week 5 after the bye in Week 4.

Ryan Mathews: Though the Chargers celebrated their 30-21 win over the defending champion Seattle Seahawks, they will hope for the best with Mathews. The San Diego running back sprained his MCL, according to the San Diego Union-Tribine, though it's unclear how much time he will miss.

Eric Decker: After catching four passes for 63 yards and a touchdown, Decker injured his hamstring and was forced to exit the Jets' game against the Packers. The Jets will hope Decker's injury doesn't keep him out for long.

Vernon Davis: The 49ers tight end injured his ankle against the Bears and did not return to the game. Davis is a key part of the passing attack so San Francisco will hope it's not too serious.

Charles Tillman: The Bears cornerback injured his triceps during the game against the 49ers. Tillman tore his triceps in 2013, which is cause for concern for the Chicago organization.

Gerald McCoy: The Buccaneers defensive lineman injured his hand, with NFL.com reporting that it might be a fracture. That would likely require some missed time from the standout player.
