Kaleb Johnson will arrive at the Baltimore Ravens' facility with a boulder-sized chip on his shoulder. The Rutgers offensive lineman was snubbed from the NFL Scouting Combine in February and then didn't get picked in the seven-round draft.

Johnson will get a chance to prove that he belongs after signing as undrafted free agent with the Ravens, his agent Eugene Lee told NJ Advance Media. Johnson will join former Rutgers offensive lineman Jeremy Zuttah, who started 16 games at center last season for the Ravens.

Johnson appeared to be on track to be an NFL Draft pick when he earned Freshman All-America honors in 2011. He moved from right to left tackle the next season and was named to the All-Big East second-team.

Johnson moved again as a junior, landing at left guard. He remained there for his final two seasons, earning honorable mention All-Big Ten honors as a senior.

Despite all of those accomplishments, Johnson, who started the final 50 games of his career, did not earn an invitation to the NFL Scouting Combine in February. Bothered by the snub, the 6-foot-4, 303-pound Jacksonville native had a solid showing at Rutgers' pro day in March, but he still didn't generate significant interest from NFL teams. Johnson's only pre-draft workouts were the local pro days hosted by the Jets and Giants.

Johnson considered leaving Rutgers after his junior season, but he returned after receiving a fourth-to-seventh round projection from the NFL Draft Advisory Board. Although returning for his senior season didn't boost his draft stock, Johnson believes he's better prepared for the NFL now.

"I know that I'm a better player," Johnson said. "Not just physically, but mentally. Understanding football is probably the biggest thing of playing at the next level and having a year with Coach (Mitch) Browning and Coach (Ralph) Friedgen has helped me tremendously."
