Perhaps the biggest tweeting trend among NFL players watching Saturday's college football games involved the gruesome knee injury suffered by South Carolina running back Marcus Lattimore during the Gamecocks' 38-35 victory over Southeastern Conference rival Tennessee.
Lattimore was carted off the field and taken to the hospital after injuring the same right knee he had surgery on last year. The school later announced Lattimore, considered one of the SEC's top running backs, would be out indefinitely.
Washington Redskins quarterback Robert Griffin III, Houston Texans wide receiver Andre Johnson and Minnesota Vikings wide receiver Percy Harvin were among the NFL players who tweeted in support of Lattimore:

Miami Dolphins wide receiver Brian Hartline was pleased with what he saw in the first half of Kent State's contest against Rutgers:
Atlanta Falcons wide receiver Roddy White was sure to remind Georgia quarterback Aaron Murray why the Bulldogs still had a chance against Florida:
The University of Arizona's huge 39-36 upset of No. 9 Southern California caught the attention of the Denver Broncos' Chris Gronkowski.
