BTCC Thruxton: Proctor substitutes for unwell Osborne, Smiley tops practice

Senna Proctor steps in for the unwell Sam Osborne in the British Touring Car Championship's fifth round at Thruxton. Osborne was hospitalized for blood tests after feeling unwell, and despite clear results, he couldn't recover in time to race. Proctor's last-minute substitution could shake up the race dynamics, especially as Tom Smiley topped the practice session. This move highlights the unpredictable nature of racing, where health issues can lead to significant on-track changes.
