In Test cricket, there is no fixed limit on how many overs a single bowler can bowl in an innings or a match.

Core rule

  • The Laws of Cricket do not cap a bowler’s total overs in Test or other first‑class cricket.
  • A bowler can keep bowling as long as:
    • The captain keeps giving them the ball.
    • They are fit enough.
    • They are allowed to bowl from that end (no injury/disciplinary ban).

Overs in a Test day

  • In Tests, the fielding side must bowl a minimum of 90 overs per day , roughly 15 overs per hour.
  • These 90 overs can be divided among bowlers in any way the captain chooses; one bowler could theoretically bowl a very large share if conditions and stamina allow.

Contrast with limited-overs cricket

  • In ODIs and T20s, bowlers usually face a strict limit (for example, 10 overs max per bowler in a 50‑over match, i.e., 20% of the innings).
  • This percentage-style cap is not applied in Test cricket, which is why long “workhorse” spells are common in Tests.

TL;DR: In Test matches, a bowler can bowl as many overs as the captain wants and the bowler can physically manage; there is no numerical maximum per bowler.
