Griffiths spent a large portion of the season sidelined with a calf injury and struggled for fitness throughout which cut down his playing time, but his manager believes the Scottish international can come back stronger in the next campaign.
Rodgers said to the Evening Times:
“It’s been unfortunate for him this year with injury, illness and bits and pieces.
“It’s probably been frustrating, but hopefully that will get tidied up and he’ll be back, fit and raring to go for pre-season.”
Griffiths joined Celtic from Wolverhampton Wanderers in 2014 and has gone on to make 183 appearances in all competitions, contributing 141 goals.
The 27-year-old has won five Scottish Premiership titles, two Scottish League Cups and one Scottish Cup, which could become two if Celtic beat Motherwell on May 19.
Rodgers has turned to Moussa Dembele and Odsonne Edouard as a result of Griffiths’ injury problems this season, but the pair could be on their way out in the coming weeks.
