Los Angeles Chargers left tackle Joe Alt was carted back to the locker room in the first half of Sunday’s road game against the New York Giants and was ruled out for the remainder of the game with a lower right leg injury. Per an ESPN report, Alt sustained a high ankle sprain. Alt was injured on the Chargers’ second possession when Giants linebacker Kayvon Thibodeaux was blocked into the Los Angeles lineman as his right leg buckled. Alt limped off the field under his own power before a cart took him back to the locker room. Los Angeles already is playing without two-time Pro Bowl offensive tackle Rashawn Slater, who is out for the season with a knee injury.
