Midfielder Wycliffe Opondo and striker Kennedy Otieno suffered ankle twists in training at the team's uneven training ground.
The club has been forced to move their training to Chania High School from their traditional Thika Municipal Stadium which has been denied access to sports activities due to on-going campaigns ahead of the general elections.
Club officials condemned the move and urged local leaders to make the construction of training grounds in the town a priority.
“We have been forced to hire training grounds and the unfamiliarity is likely to have an impact on the team. We hope the new county will not just pay lip service to this hugely important issue," the club's team manager George Maina told their website.
Thika United coach John Kamau termed the injuries to the duo as a small set-back one that he remains confident he can overcome as he faces his second match.
It is a match Kamau cannot afford to lose especially after his side went down 1-0 to Sofapaka in the season opener. The team finished fifth last season and are looking to do better this season.
