The Notre Dame product left the game against the Pittsburgh Steelers on Monday to get his right ankle re-taped, but later re-entered the contest, missing just three snaps.
Rookie Denzel Perryman replaced Te’o in the starting lineup.
Te'o leads the Chargers with 41 combined tackles through five games.
Asked if Te'o will play on Sunday, Chargers head coach Mike McCoy said the team is taking a wait-and-see approach.
Perryman would likely start for Te'o if he can’t go.
“Every player is working hard to get out there,” McCoy said. “We’re going day-to-day with everybody right now, so we’ve got a couple days before we play. We’re hoping everyone can play.”
Last season, Te'o suffered a fractured right foot Week 3 against the Buffalo Bills -- the same foot in which he suffered a fractured right bone in August 2013 of his rookie season that forced him to miss the first three regular-season games and ultimately required offseason surgery to repair.
Te'o also suffered a sprained left foot that forced him to miss the final two preseason games of 2014. In total, Te'o has missed nine regular-season games in three seasons.
Te'o had a shoulder issue during exhibition play, and did not play in the final two preseason games.
Along with Te'o, tackle King Dunlap (concussion), guard Chris Hairston (ankle), receiver Stevie Johnson (hamstring), cornerback Craig Mager (hamstring), defensive lineman Darius Philon (hip, thigh), center Chris Watt (concussion, groin) and linebacker Tourek Williams (foot) did not practice.
