The left-back had been out of acton since January with lower leg discomfort, but he made his comeback on Thursday night against Benfica by coming off the bench.
Tierney could now start against Manchester City on Sunday as Arsenal play host to the Premier League leaders.
Rob Holding could come into the defence, while in attack Alexandre Lacazette, Gabriel Martinelli and Nicolas Pepe are all pushing to start.
Arteta has a number of selection headaches given Arsenal have a busy schedule, which includes the second leg of their last-32 Europa League tie with Benfica next Thursday.
And, given Arsenal are 10th in the Premier League, winning the Europa League looks like their best bet of getting back into the Champions League.
