Professional career
Philadelphia Eagles
Avant was drafted in the fourth round of the 2006 NFL Draft by the Philadelphia Eagles. The Eagles traded a sixth round draft pick and tackle Artis Hicks to the Minnesota Vikings for the pick used to take Avant. In a post-draft interview, Eagles head coachAndy Reid said Avant "has great hands, toughness, leadership; he's very intelligent and a good route runner." Scouting reports projected him as a consistent possession receiver who lacked the speed to be a deep threat. As a part of the Eagles crowded receiving corps, Avant saw limited playing time with the offense in his rookie season. He had his best performance—four receptions for forty yards and one touchdown—in the final game of the season, while the Eagles rested their starters for the playoffs. After the 2009 season, in which he set new career-highs in all three categories with 41 receptions for 587 yards and 3 touchdowns, Avant was named to the USA Today All-Joe Team for his stellar play in the slot position. 32 of Avant's 37 catches on third down resulted in a first down. He was re-signed to a five-year contract on March 8, 2010. He was named the Eagles' Ed Block Courage Award recipient for 2010. Avant was released from the Philadelphia Eagles on March 4, 2014.

Avant is a Christian. Avant has spoken about his faith saying "I devoted my life to Jesus Christ on May 4, 2003. It was a day when, if you can imagine it, your eyes are opened to a whole different light. On that day, I had a consciousness of God that I never really had before. It’s sort of like being in darkness, but you finally start to see. I realized that day that all of the stuff that I learned growing up was backwards, according to the Scripture. It was the day that changed my life. I started realizing that I had a purpose, and every thought from that day on went through a filter of Jesus Christ first. Before I can make a decision I have to think, ʻWould it be pleasing to God?’". As of 2017, Avant opened up and runs Launch, a trampoline park in Deptford, NJ.
