The AFL confirmed the Australian Sports Anti-Doping Authority (ASADA) notified the league that the two players had tested positive in an ‘A’ sample for Clenbuterol.
Both Thomas and Keeffe are now provisionally suspended with their ‘B’ samples set to be tested on April 14.
An AFL statement said Thomas and Keeffe provided the samples on February 10, before ASADA informed league and the players of the positive result last Friday.
“Clenbuterol is not a specified substance on the AFL anti-doping prohibited list and as such, requires the players to be provisionally suspended,” the statement read.
“It’s important to note that until the outcome of the ‘B’ sample is known, the commencement of the provisional suspension is not an admission of guilt or wrongdoing, but a procedural requirement under the AFL anti-doping code.”
Collingwood opens its season against the Brisbane Lions on Saturday at the Gabba before meeting Adelaide on April 11, however Thomas and Keeffe will not be eligible to play in either game due to their provisional suspensions.
The news comes just a week after it was revealed Fremantle star Ryan Crowley has been provisionally suspended since September last year after he failed a doping test.
Tomorrow, the AFL Anti-Doping Tribunal will make known its findings into the 34 current and former Essendon players involved in the 2012 supplements program.
