INDIANAPOLIS -- Phillip Walker's fourth-quarter, 29-yard touchdown pass to Justice Liggins was enough to give the Colts a 7-6 win over the Bengals in a fourth and final preseason game full of position battles.
With less than 48 hours until rosters will be cut to 53, both Cincinnati and Indianapolis had undecided key spots. Each team walks away with a lot of uncertainty still remaining.
Walker got Indianapolis its second win of the preseason, but the focus was on Scott Tolzien and Phillip Morris -- two quarterbacks fighting for the right to be Andrew Luck's backup and the de facto Week 1 (or longer) starter. Luck is recovering from January shoulder surgery that's left him on the physically unable to perform list throughout training camp. While he is expected to be removed from the PUP list by Saturday's 4 p.m. deadline, his status for the Sept. 10 season opener at the Rams remains in doubt.
Tolzien and Morris each led the Colts on two drives before Walker entered, playing the entire second half and finishing 2 for 9 with one interception and the game's only touchdown. Tolzien completed 4 of 5 for 24 yards; Morris hit on 2 of 5, including a 51-yard long ball to JoJo Natson.
Bengals kicker Randy Bullock is trying to shake mishaps from a season ago and cement his spot in Cincinnati. Bullock missed what would have been a winning kick against Houston in 2016, and on Thursday night he whiffed on a potential 47-yard go-ahead kick with 1:50 left in regulation. But Cincinnati's Jake Elliott didn't do himself any favors, either. Despite the distance, Elliott missed a would-be 60-yarder as time expired.
Cincinnati started AJ McCarron, ensuring quarterback Andy Dalton a clean bill of health when the Bengals host the Ravens on Sept. 10. McCarron was forced to come back in after his backup, Jeff Driskel, left with a thumb injury. Driskel was 2 of 3 for 21 yards. McCarron ended the night 20 of 30 for 216 yards.
Bengals first-round wide receiver John Ross caught one pass for 6 yards before leaving with a knee injury.
PLAYING IT SAFE
Cincinnati and Indianapolis didn't let most of their starters see the field. Fantasy football owners can rest easy knowing the Bengals' A.J. Green, Dalton and rookie RB Joe Mixon were just a few of Cincinnati's starters who stayed put on the sideline. Indianapolis Pro Bowl wide receiver T.Y. Hilton and running back Frank Gore also didn't see action.
Earlier this week the Colts announced that Pro Bowl cornerback Vontae Davis will miss time witha groin injury. That opened the door for second-year safety T.J. Green, Indianapolis' 2016 second-round pick who is still trying to solidify a spot in the Colts' secondary after being moved from safety to cornerback during training camp. However, Green (shoulder) did not dress, missing his opportunity to prove he is a viable fill-in for the injured Davis.
