"Things are going quite well with ‘Boro’ and Frings but we’ll have to see how things develop," Bremen co-trainer Wolfgang Rolff was quoted as saying by the club's official website.

"Should their progress continue, they will be able to take the next step by next week. That doesn’t mean they’ll be back in team training next week. There is no time frame established for that yet."

German international midfielder Frings has been suffering from cruciate ligament damage, sustained during pre-season preparations.

Borowski sustained outer-ligament strain during Bremen's Bundesliga opener against Bochum.
