Saracens prop Mako Vunipola limped off with an ankle injury early in the game against Leicester with the out-of-favour England prop now faces a spell on the sidelines.
Then men in black moved up to second place in the Premiership by beating the league leaders 34-27 in a entertaining game.
“It doesn’t look great. It’s such a shame because he’s been playing such wonderful rugby,” Saracens boss Mark McCall said.
Leicester’s losing bonus point sees them 12 points above Sarries, who are one clear of Harlequins and with a game in hand.
