Jacobs' MRI exam showed no structural damage in his knee. He said on ESPN First Take on Tuesday that he hopes to play in the Giants' game against the Cardinals on Sunday but that the team might hold him out of the game for precautionary reasons.
Jacobs gained 73 yards on 11 carries in the 30-10 victory over the Baltimore Ravens that raised New York's record to 9-1. He left the game in the second quarter and returned for just two carries in the third as Derrick Ward and Ahmad Bradshaw took over. They helped the Giants rush for 207 yards against a team that had been leading the league in rushing defense, allowing just 65 yards per game.
"There is a little swelling, he is walking really well," Coughlin said of Jacobs, fourth in the NFL with 879 yards rushing. "They are going to do all of the tests. But hopefully we can get this under control."
Asked which knee it was, Coughlin replied: "If you don't know which one it was, I'm not telling you."
Cornerback Aaron Ross, who had two interceptions, returning one for a touchdown, also underwent an MRI exam on his hamstring. Coughlin said Ross had aggravated an injury he had earlier in the year.
Both Jacobs and Ross said after the game that they could have returned to the game if needed.
