Less than a day after agreeing to sign with the Eagles during the league's legal tampering period, running back Frank Gore reconsidered and pulled out of his deal with the team Monday.

According to ESPN's Adam Schefter, it wasn't just about the money for the veteran, who reportedly is strongly considering signing with the Indianapolis Colts when the league year officially opens Tuesday at 4 p.m.

"He was telling people, 'I am going to the Eagles,'" Schefter said Tuesday during an appearance on ESPN Radio's Mike and Mike In The Morning. "'I have a deal in place.'"

However, after thinking about his decision, Gore started to have second thoughts sometime Monday, Schefter said.

"Yesterday morning, I got a phone call saying, 'You need to track Gore. He's getting cold feet here,'" Schefter said. "Now, the Eagles are onto other running backs. The Colts are on to Frank Gore as they were on Saturday, when they were talking about numbers but not exchanging offers. The Colts at that time had big money on the table. The Eagles came along and said, 'We have even more big money on the table.'

"On Sunday night, [Gore] called some people and said, 'I'm not feeling this. I should feel happy, I should feel excited right now and I'm not feeling it,'" Schefter said.

"A lot of people when you make a decision, you listen to your gut, and he obviously wasn't feeling it. So, now Frank Gore is back on the market and a lot of guys are back on the market."

At 31 years old, this is likely the final chance for Gore, who rushed for 1,106 yards and four touchdowns last season, to cash in via free agency.

The Eagles and Gore reportedly agreed to a three-year contract with $7.5 million in guarantees.
