Washington, DC (SportsNetwork.com) - Washington Nationals outfielder Jayson Werth will undergo surgery Friday to repair the AC joint in his right shoulder, according to the Washington Post.

Werth is expected to be sidelined between 2-to-3 months, putting his availability for the start of the 2015 season in question. The Nationals have yet to confirm that the veteran slugger is headed for the procedure.

The 35-year-old initially hurt his shoulder while making a catch against the Philadelphia Phillies in early August. Werth missed a week with the injury, but batted .339 over the final 35 games of the regular season after returning to the lineup.

In 147 overall regular season games in 2014, Werth hit .292 with 16 home runs and 82 RBI to help Washington win a National League-best 96 games.

Werth, entering the fifth season of a seven-year, $126 million contract he signed with Washington in December of 2010, has had an eventful offseason. He was sentenced to 180 days in jail, 170 of which were suspended, after being found guilty last month of reckless driving in Fairfax County, Virginia during the summer.
