CHARLOTTE, N.C.(AP) -- For a speedy guy, football success has come
slowly for Sherrod Martin.

He had to wait a year after high school before enrolling at
Troy, then was hampered by two shoulder surgeries and a broken
hand in college. Martin was buried on the depth chart at
cornerback in his first training camp with Carolina. The
Panthers then moved him to safety, only to see him slowed by a
bruised knee.

Two months of waiting ended Sunday, when an injury forced the
25-year-old rookie into the starting lineup at free safety.
Martin responded with two of Carolina's five interceptions in an
upset win over Arizona, a performance that could earn the
second-round pick the permanent starting job.

"When they put him back there at the safety position, just
watching him in practice, you could tell he felt very
comfortable playing that position," reserve cornerback Dante
Wesley said Wednesday. "To me, it really showed on Sunday how
valuable he is."

Forced into action because of Charles Godfrey's right ankle
injury, Martin doubled Godfrey's interception total in his 22
games as a starter. Martin raced across the field to grab Kurt
Warner's overthrown pass in the second quarter. Then after Chris
Gamble forced a big hit to pop the ball free early in the fourth
quarter, Martin was there for another pick that set up a field
goal for a 31-14 lead.

"It was just me running to the ball, something we preach about,"
Martin said. "It just put me in the right place at the right
time."

It appears the 6-foot-1, 198-pound Martin is now playing the
right position, too, after taking a difficult path to the NFL.

He was in Troy's recruiting class coming out of high school, but
didn't enroll until the following January and spent a year out
of football. He then had surgery on both shoulders that forced
him to redshirt as a junior. He returned the following season
only to be slowed by a broken hand.

He then moved from cornerback to safety as a senior and had an
NCAA record three interceptions in one quarter against Alcorn
State.

"It just made my work ethic better. Two shoulder surgeries, a
broken hand, I always felt like I was behind," Martin said. "So
I really take a lot a pride in working out in the weight room
and things like that, the little things."

When Carolina took the Griffin, Ga., native with the 59th pick
in April's draft, the Panthers figured he'd be the No. 3
cornerback. The job was open after Ken Lucas was released and
Richard Marshall was promoted to starter.

"He's kind of a tweener guy. He was in college, both as a corner
and as a safety," coach John Fox said. "It's a good skill set to
have."

But Martin soon became lost in training camp. He plunged down
the depth chart after being outplayed by seventh-round pick
Captain Munnerlyn, who earned the nickel back job.

"Captain, he's really been doing a real good job. We motivate
each other. We talk on and off the field," Martin said. "When
you see somebody with you doing good it only pushes you and
forces you to take your game to the next level, also."

Injuries led the Panthers to switch Martin to safety, but he
bruised his knee in the third exhibition game and was relegated
to special teams once the regular season started. That changed
when Godfrey was hurt in Carolina's loss to Buffalo on Oct. 25.

The Panthers entered the Arizona game with only three
interceptions in six games. They intercepted Warner five times,
with Martin taking two game balls home with him.

"I couldn't have asked it any other way," Martin said of his
debut.

Godfrey was no longer in a cast Wednesday, but he didn't
practice. Martin figures to start again Sunday against unbeaten
New Orleans and its No. 1 ranked offense.

Fox was noncommittal when asked if Godfrey would regain his
starting job when he's healthy again. If Martin turns in a
repeat performance, it may be Godfrey's turn to wait.

"When his opportunity came he made the best of it," Marshall
said of Martin. "He made some great plays for the defense and we
hope he continues to do it this week."
