Restricted free-agent running back Lance Ball signed the one year, $1.323 million dollar tender offer from the Denver Broncos yesterday. Ball has been a part of Denver’s backfield rotation since 2010. Last season he rushed for 158 yards and a touchdown on 42 carries and caught 7 passes for 61 yards and a score. Ball’s salary does not become guaranteed unless he makes the Broncos’ season-opening roster.
