Beck was sent off for Rovers in today's 0-0 draw with derby rivals Preston.
Before his red card, Beck appeared to be bitten in the neck by Preston's Milutin Osmajic.
"Obviously that's what happens in local derbies, emotions get very high," said Rovers boss John Eustace. "You can see from the television pictures that the kid has taken a big chunk out of his neck. That's part of being in the derby, I suppose.
"(Owen) said he was sent off for the tackle, he's tried to kick the ball away and the lad has made a big scene of it. It's a harsh one, we are disappointed to have now lost him for three games. We just have to make sure Owen is okay now."
Beck's red card came after a melee two minutes before fulltime.
