Villarrial's injury, which occurred in the nine-on-seven running drill, could cost the Bears six or seven weeks without a key member of an offensive line that gave up a league low 17 sacks last season. The 6-3, 310-pounder also anchored the running game, while starting 62 of 64 games over the past four seasons.
For the time being, rookie third-round draft pick Terrence Metcalf will fill in for Villarrial. Leaving the Bears with two inexperienced players on the offensive line to start the season.
He was injured on a running play and it came just one play Merritt had made a diving catch along the sidelines. He could miss as many as 10 weeks. There has been talk of placing him on injured reserve meaning he would miss the entire season.
Also, backup center Kevin Dogins was sidelined with a strained right side and is listed as day-to-day, and veteran cornerback Floyd Young, signed this off-season from Tampa Bay, was released with an injury settlement.
