The Philadelphia 76ers worked out with a trio of free-agents and a G-league player this week.

The team is currently looking to fill the void in their lineup. It is due to the unavailability of rookie Zhaire Smith and second-year man  Markelle Fultz, who are out with injuries.

According to Sharms Charania of The Athletic, the Sixers worked out with veteran guards, Arron Afflalo, Brandon Rush, and Sean Kilpatrick.  G-league wing Haywood Highsmith also joined the workout session.

While the Sixers' starting five is doing a good job, their substitutes are seemingly struggling. The team currently needs another solid player who can contribute from the bench.

According to Timothy Rapp of Bleacher Report, the Sixers' game against the Toronto Raptors exposed their problems on their bench. The Raptors' reserves outscored the Sixers', 41-18. Philadelphia eventually lost that matchup, 113-102.

The 11-year veteran Afflalo last played for the Orlando Magic last season. He had a solid decline in his numbers for the team, however, it can be attributed to his scarce playing time. In 53 games the previous year, he averaged only 12.9 minutes, 3.4 points and 1.2 rebounds per game. What's impressive is his 38.6 three-point shooting percentage.

Kilpatrick played for four teams last season. Namely, the Brooklyn Nets, the Milwaukee Bucks, the Los Angeles Clippers and the Chicago Bulls. He averaged 6.3 points per game in 53 games that year. Among them, he had a successful run with the Bulls as he averaged 15.4 points per game in nine games with the team.

Rush, meanwhile, did not see action last year. He last played for the Minnesota Timberwolves in the 2016-17 season with an average of 4.2 points per game.
