Scott Speed's formula one career could have ended in a Nurburgring gravel trap.
According to the website of American broadcaster Speed TV, the Toro Rosso driver risks being replaced ahead of the Hungarian grand prix following a physical altercation with his team boss Franz Tost on Sunday.
It is claimed that the pair nearly came to blows in the team garage after Speed returned to the garage, and one witness described the scuffle as "assault" by Tost.
American Speed, 23, is quoted as saying: "It's clear that from my bosses me and Tonio both have very little support."
Tost and team co-owner Gerhard Berger are openly courting both Sebastien Bourdais and BMW's Sebastian Vettel for 2008, leaving the Italian team's current pairing aware that their days at Toro Rosso are probably numbered.
"It doesn't take a rocket scientist to read the press and know that Franz and Gerhard are pushing like hell to get rid of me and Tonio," Speed admitted.
