The fifth-round draft pick from Vanderbilt broke part of a vertebra in his lower back in the second quarter of the preseason opener against the Detroit Lions on Thursday night.
The team has not decided whether to place Goff on injured reserve or give him more time to recover. If he is placed on injured reserve, he cannot play or practice with the team this season.
Browns: Released Gary Baxter , ending the safety's hopes of making a comeback from knee surgery this season.
The Browns released Baxter four days after he underwent arthroscopic knee surgery to remove loose cartilage.
Baxter tore both patellar tendons on the same play in a 2006 game against Denver. The 29-year-old sat out last season while rehabbing and switched from cornerback to safety in an attempt to extend his career.
PATRIOTS: Signed cornerback Jeff Shoate and placed safety Tank Williams on the injured reserve list.
Terms of the deal with the 27-year-old Shoate were not disclosed Saturday.
The 5-foot-10, 180-pound Shoate has played in 14 NFL games, all with the Denver Broncos.
Denver selected Shoate in the fifth round of the 2004 NFL Draft and released him Dec. 4, 2007. He was signed to the Baltimore Ravens practice squad eight days later and he ultimately joined the New York Giants practice squad during last season's playoffs.
The Patriots signed Williams on March 6. The 6-2, 223-pound free agent has 59 starts in six seasons for the Tennessee Titans and Minnesota Vikings.
LIONS: A torn Achilles tendon will sideline cornerback Stanley Wilson for the rest of the season. The four-year veteran suffered the injury during Thursday's exhibition win over the New York Giants.
The injury typically requires 10 months to a year of rehab after surgery.
Wilson, a third-round selection in 2005, started the first five games at right corner last season but went on injured reserve with a knee injury Nov. 28. He's started nine of the 32 games he's played for Detroit.
JAGUARS: Defensive end James Wyche was placed on the waived/injured list with a torn Achilles tendon.
The Jaguars, looking for help at defensive end with first-round pick Derrick Harvey still a holdout, signed veteran free agent Bo Schobel.
The 27-year-old Schobel played two games for Arizona last season. He was waived by the Cardinals on July 21 and was in uniform for Saturday night's preseason game against Atlanta.
Schobel, a fourth-round draft pick by Tennessee in 2004, was with the Titans for two seasons before playing in 14 games for Indianapolis in 2006.
