HOUSTON -- The Houston Texans have signed quarterback Josh Johnson to the active roster and released quarterback Matt McGloin, the team announced Tuesday.

The Texans added McGloin last week after rookie quarterback Deshaun Watson tore his ACL during practice on Thursday. McGloin was inactive on Sunday, as Tom Savage started in the 20-14 loss to the Indianapolis Colts, with T.J. Yates as Houston's backup.

Watson is scheduled to undergo ACL surgery on Wednesday with Dr. Walter Lowe in Houston, a source told ESPN.

Johnson was the New York Giants' backup quarterback in 2016 but was released in September 2017. He has not played in a game since the 2013 season, and in the two games he did play that year, he did not throw a pass. He played in one game in 2012, and did not throw a pass in that game, either.

During the 2011 season for the Tampa Bay Buccaneers, Johnson was 19-of-36 for 246 yards, with a touchdown and two interceptions in nine games.
