Tracy left Sunday's game at Houston due to a hamstring injury, Jordan Raanan of ESPN.com reports.
Tracy made his way off the field slowly with 5:29 left in the second quarter and was deemed questionable to return not long afterward. At the time of his exit, he had six carries for 15 yards and one touchdown and one catch (on one target) for two yards. Cam Skattebo and Devin Singletary will handle the Giants backfield for as long as Tracy is sidelined.
