After a nasty collision with Yoan Moncada earlier this week, Chicago White Sox outfielder Willy Garcia could miss the rest of the season after suffering a broken jaw.

The collision, which took place in Monday’s game agains the Toronto Blue Jays, knocked Moncada out for a few days, but Garcia will miss significantly more time, the team announced Thursday.

Garcia will be out for four to six weeks after undergoing surgery to insert a plate into his right jaw, the White Sox said. He was originally diagnosed with a concussion, which landed him on the seven-day disabled list, but a CT scan this week revealed a fractured right jaw.

In 105 plate appearences this season, Garcia has a .258 batting average, with two home runs and 11 RBi for the White Sox.  

Meanwhile, Moncada will return to the team’s lineup when they take the field against the Boston Red Sox at Fenway Park Thursday night. He missed the team’s last two games after banging his knee into the side of Garcia’s head while chasing down a fly ball off the bat of Darwin Barney.

Moncada is hitting .105 with a home run and six RBI in 46 plate appearances in his brief White Sox career.
