Andrus, who signed with the Indianapolis Colts in 2006 after going undrafted out of Murray State, finally got his chance to kick in the NFL regular season last year, serving as the Colts kickoff specialist in week one before they released him. He then played in three games for the Tampa Bay Buccaneers, where he was a perfect 10-for-10 in PATs but missed his only field goal attempt, and they too let him go.
Finally the Niners, after injuries sidelined both Nedney and week 16 fill-in Ricky Schmitt, gave Andrus the chance to join them in St. Louis for the regular season finale, where he made all four of his PATs but did not get to try any field goals.
Though he's never done so in a regular season game, Andrus also handled the punting chores in college, meaning that he might be available to give Lee some plays off here and there in camp. Primarily though he’s on the team to serve as insurance in the event that Nedney gets dinged again. While he should get ample opportunity to kick during the pre-season, realistically he has no chance to make the 49ers barring injury. Of course, Andrus understands this. He might be wearing a Niners jersey during July and August, but really he'll be auditioning for the other 31 teams out there.
