Weeden began the season again as Romo's backup. During a Week 2 game against the Eagles, Romo fractured his clavicle and Weeden closed out the win. It was announced that Romo would be placed on short term IR, which left him designated to return November 22, and that Weeden would be the starter at quarterback. Even though he was preparing to be the starter, with owner Jerry Jones and head coach Jason Garrett commenting on his positive progress, the Cowboys covered themselves by also trading for Matt Cassel on September 22. Weeden started three games, completing 71 percent of his attempts for 666 yards and one touchdown with two interceptions, but lost all three games. Despite his inconsistent play Weeden was a much loved player within the Cowboys fanbase. So much so that "Weeden 4 Life" became a popular online rallying cry by fans who wanted to show their support for the Quarterback.  On October 13, the Cowboys decided to bench him and instead play Cassel, who started four games (all losses). On November 17, he was waived to make room for Romo, with the team deciding to keep Cassel as the main backup. 
In 2012, Jerez started 32 games with the Short-Season A Lowell Spinners before missing the remainder of the season with hand injury. Prior to injury, Jerez batted .241 (20-for-83) with five RBI and three stolen bases. Then in 2013, he appeared in 38 games and hit a paltry .138 average in 38 games while playing right and centerfield for Lowell. But Jerez turned his career around after moving from outfield to pitcher in 2014. In that season, he posted a 3–1 record with a ERA and one save coming out of bullpen for the GCL Red Sox. He ended the season at Lowell, going 1–1 with a ERA.
