This from the official site:
We're delighted to confirm that Alex Harris, pictured, has re-joined The Bulls following his departure from Gloucester City earlier this week.
The 'keeper who made 29 appearances for Hereford last term, had initially agreed a deal with Bulls boss Pete Beadle to stay at Edgar Street this season, but opted to make the step up to the National South after being given permission to talk to Gloucester by The Bulls in May.
Having seen his chances limited for The Tigers this season, Harris mutually agreed to leave Gloucester at the start of the week.
Speaking to the official Hereford FC website, Bulls boss, Pete Beadle said "we're delighted to welcome Alex back to Edgar Street.
"He is obviously someone we know all about, having been an instrumental part of last season's title winning squad. Alex will provide some tough competition for both Martin Horsell and Max Harris.
Alex trained with The Bulls on Thursday evening, but will play for Lydney on a dual registration basis this weekend.
