Tight end Evan Rodriguez, a fourth-round pick out of Temple, agreed to a four-year deal with the Bears.
Financial terms were not disclosed.
A two-time first-team All-MAC pick, Rodriguez was the 111th overall pick last month. He caught 69 passes for 871 yards and seven touchdowns during his Temple careeer.
Rodriguez joins second-round pick wide receiver Alshon Jeffrey and seventh-round pick cornerback Greg McCoy as Bears draft picks to agree to deals.
