While Brown rested Graham for most of the second half of the game, the Browns built on their lead with an 87-yard rushing touchdown by rookie Don Phelps and another score by Rex Bumgardner. Phelps suffered a head injury in the game and did not remember making the run, the longest rush from scrimmage in team history to that point. He got X-rays after the game and spent two nights in the hospital after being diagnosed with a mild concussion. Brown was pleased with the team's performance after just three weeks of training camp, saying Phelps "looked a knife cutting across the field". Cleveland beat the Baltimore Colts, a rival from the old AAFC, in its second preseason game. Scoring in the game, played in Cincinnati, began with an 18-yard passing touchdown from Graham to halfback Dub Jones in the first quarter. Baltimore's Billy Stone received the ensuing kickoff and ran it back 100 yards for a touchdown to tie the game at 7–7. Graham then led the team on a 75-yard drive composed mostly of passes to Lavelli that ended with a one-yard touchdown by Graham on a quarterback sneak. A short field goal by Groza gave the Browns a 17–7 lead at halftime. The Browns widened the lead with another Groza field goal in the third period and a touchdown set up by a 63-yard punt return by Ken Carpenter at the beginning of the fourth. Holding a 20-point lead, Brown rested his starters and sent in a squad composed entirely of rookies. The rookies managed another touchdown on a two-yard rush by Tom O'Malley that was set up by a Carpenter interception, giving Cleveland the 34–7 win. Cleveland's defense played well, allowing 42 net rushing yards and 86 passing yards. Cleveland won its third preseason game in a row over the Detroit Lions at the Rubber Bowl in Akron, Ohio. Graham threw a touchdown pass to Jones on the team's second offensive play after receiving the opening kickoff, the first of three touchdowns in the first quarter. The second score came on a one-yard rush by Graham set up by several passes to Jones on the team's second possession. The third was an eight-yard run by Rex Bumgardner at the end of the quarter. Neither team scored in the second quarter, although Cleveland had two touchdowns called back because of penalties. A 41-yard rushing touchdown by Motley extended Cleveland's lead to 28–0 in the third quarter, and Brown rested his starters. With Cleveland's best players out of the game, Detroit scored two touchdowns in the fourth quarter on a pair of two-yard rushes by Dan Sandifer and John Panelli.
